Two input ports ("
In A
", "
In B
") can be switched to one output port ("
Out
"). The
unused input port is terminated internally. The module is able to pass an external
10 MHz reference signal.
The module provides RF level monitoring, i.e. the RF level of both input ports is
measured and is compared with (adjustable) RF threshold levels. This enables the
event indication functionality with respect to the present input signal levels, and/or
permits the DEV 1953 to control the switching autonomously.
3.2.2 DEV 11-0026

The functionality of the module DEV 11-0026 is identical with the module
DEV 11-0014 (please refer to chapter 3.2.1), but the module is designed for 75 Ohm
with F connectors (instead of 50 Ohm with SMA connectors).
